Reddit reviews DisplayPort to DVI Adapter for Select Dell OptiPlex Desktops / Latitude / Alienware Laptops / Precision Mobile WorkStations CN-023NVR

I have done some multigpu stuff, but in Linux, not windows. The first thing I can say is that you DO NOT WANT TWO GPU SOFTWARE SYSTEMS. In fact, I would disable all of the ride along software from both vendors.

1. Use DDU to uninstall ALL vendor display software.
   
   
2. Install the drivers for one video card and ONLY the drivers ( No Play.TV, no GeForce Experience, No Raptr, etc. Only install the drivers, none of the fancy additions.).
   
   
3. Install ONLY the drivers for the second video card. Again, ONLY install the drivers, no enhancement software.
   
   Anything that tweaks settings automatically is bad. Even then, this is not a guaranteed fix. The problem is that you are doing something interesting, and the tools provided by your hardware vendors are not meant for interesting setups. They are meant to make out of the box uses work. When you stick two cards in from two vendors, you need to take all of the functions that would be handled by the nice little package, and do it yourself because your situation is now unique. I hope the purge and drivers only install works for you. If not feel free to shoot me a message and we can dig deeper into what the exact problem is, but be prepared for it to get hairy. Interesting setups take work to understand and maintain, but you can learn a TON doing it.
   
   Alternatively, if that doesn't sound like your cup of tea, buy this and use one video card.
